Embodiment Construction

[0014] Referring to FIG. 1 , the hinge 200 in the embodiment of the inventive hinge includes a shaft 21 , a cam 22 , a compression spring 23 , a torsion spring 24 , a sleeve 25 , and a card 26 .

[0015] Two spokes 211 radiate outward from one end of the shaft 21 . The two spokes 211 are located on the same diameter and support a spoke wheel 212 at the same time. The other end of the shaft 21 defines an annular groove 213 for fastening the card 26 . A fixing hole 214 for fixing one end of the torsion spring 24 is defined in the middle of the shaft rod 21 .

[0016] Please refer to figure 2 As shown, the cam 22 includes a cam end 221 , a fastening end 222 and a central barrel 223 , the entire length of which is less than the distance between the fixing hole 214 on the shaft 21 and the spoke wheel 212 . Wherein the end surface 2210 of the cam end 221 has two convex peaks 2211 protruding, the two convex peaks 2211 are located on the opposite sides of the end surface 2210, both...

Abstract

The hinge comprises an axial rod with a torsion spring, a cam, a middle drum up-press spring, a sleeve coated on torsion spring with one end extending a convex arm inserted with said block end, and a card; Wherein, the cam comprises a cam end with end surface protruding peak, a block end, and a middle drum connected two ends; radiating spokes outward from one end of axial rod to prop on cam end and a sleeve with ring block slot from another end of axial rod; blocking the sleeve by card in the slot; fixing one end of torsion spring on axial rod and another end on sleeve. This invention forms an integer with stable structure.

Description

【Technical field】 [0001] The invention relates to a hinge, in particular to a torsion spring hinge, and also relates to a mobile phone using the hinge. 【Background technique】 [0002] In a foldable or clamshell mobile phone, the connection between the body and the rotating body is usually realized by a hinge. Please refer to Figure 5 As shown, U.S. patent specification US-6321415 discloses a hinge 10 for connecting a mobile phone body and a rotating body, including a shaft 12 with a washer at one end, and a spring 14 that is sequentially sleeved on the shaft 12, and a cam 16 and a follower 18, wherein one end of the spring 14 is fixedly connected to the cam 16, and the cam 16 has an elongated projection 161 along the axial direction, and the follower 18 completely wraps the end of the shaft 12 therein. When combined with a mobile phone, the hinge 10 is accommodated in a correspondingly provided accommodating space on the mobile phone body, and the end of the shaft 12 beyon...
